How payment works
Every model is gated by the x402 HTTP payment protocol. Call an endpoint and you receive a 402 Payment Required response with payment instructions. Complete the Solana USDC payment, then retry with the payment proof header — your inference runs automatically. No accounts, no API keys, metered per request.
